ISL28218FBZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28218FBZ is a dual-channel, low-noise, rail-to-rail output operational amplifier manufactured by Renesas Electronics Corporation. It features a gain-bandwidth product of 4 MHz and a slew rate of 1.2 V/µs. The device operates with a supply voltage range of 3 V to 40 V (single) or ±1.5 V to ±20 V (dual). Key electrical specifications include an input offset voltage of 40 µV, input bias current of 230 nA, and input voltage noise density of 9 nV/√Hz at 1 kHz. It consumes 850 µA of supply current per two channels and functions within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FBZ' corresponds to the SOIC-8 tube package variant. Confirm RoHS compliance status as indicated in official datasheets. Ensure the ordering part number matches the required channel count and package style before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high common-mode voltage rejection is required due to its wide 40 V supply range. Compare against lower-speed alternatives if bandwidth requirements exceed 4 MHz. Verify that the 230 nA input bias current meets the source impedance constraints of the application circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the ISL281xx/ISL282xx family of precision amplifiers. It serves as the dual-channel counterpart to the single-channel ISL28118. The FBZ designation specifically identifies the surface-mount SOIC-8 package configuration offered by Renesas.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same family include the ISL28118 for single-channel applications. Cross-family replacements require verification of gain-bandwidth and supply voltage compatibility.
